Left 4 Dead 2

Hello , Steam, I want to copy the entire of game files in SteamApps for one of my friend and becasue of some unknown reason He said Don't give me back up s ! I want to know if I do it can he get access to my account or get any info of it or like this? Please Help !

He's just trying to pirate the game. And no, he won't be able to access Your Account or anything. Tell him to buy the damn game, Jesus.Valve games are something I wouldn't torrent due to too many patches and Steam-related stuff.

If you paid for these, why not just download them through Steam on your other computer?Maybe because you are pirating them?

It's not him, it's his friend.The only good reason to copy games from Your PC to a different one is due to connection problems. Or lazyness. I always transfer them when I don't want to sit for hours doing nothing while they're downloading.(Well, not nothing, but Y'know, it's boring)

you can copy the folders over to his steam folder. he wont be able to play them unless he has purchased them. anyone that purchased them will be able to play the game if they log into their steam account on his pc. I've done this to avoid "long downloads"; just transfer thru wired gigabit to all my pcs.
